Wow. I've heard so many kewl things on 2.3 (like datetime and sets and
sum) that I can't imagine having to work in 2.2 or earlier anymore...

2.4 has worked heavily on optimization. So lots of code runs faster on
2.4. There's also a new Decimal type, generator expressions, reverse
iterators, built-in set objects, simpler string substitutions, and
decorators for functions and methods.

Generally yes. And there's no reason you can't install 2.4 in another
directory and try both versions for a while to see which one you like
better. Just make sure your !# line points to the right version.

I can't see any reason why not. Backwards compatibility is a biggie with
Python releases and I haven't heard of anything in the new release that
"breaks" older ways of doing things.
